That having said, all customization of current dslrs is a joke given the fact that you've got an embedded computer in your hand. Even on my 25 year old eos620 with date back, I could program in custom shutter-aperture curves!

How did you that?

...btw, the "embedded computer" from our hands is a monster, (especially if we talk about DiGIC 5) with a screen which has 1,040,000 dots. Remember, desktops and after that laptops had for many years a resolution of 1024x768 which means 786,432 dots...

I think that their main problem is that they are locked in pre-iPhone mindset. We have a super-CPU to do just one thing and it can do just in one way. Today the cameras are digital but still built with a mechanical mindset.

Guys, unlock that potential...

It's not the Date Back which has these capabilities it's the Technical Back E (It fits EOS 620, 650,600,RT)It has never been matched 100% It could program these curves, it could store technical data (shutter, aperture, FL, etc) about as much as 360 shots, it could imprint data on film (there was a small keyboard for that) and ... it could bracket up to nine shots with steps or 1/4th of a stop!

+1 ... I'm still missing the technical back on my old eos rt (next to the stellar release time)! The custom curves haven't been matched yet, it's still just a fixed "creative zone". It's really disappointing how the potential of the embedded cpu lies dormant, that's why I like Magic Lantern so much.
